By the end of the fifteenth century, manuscripts of Persian poetry typically were written in a script known as nasta'liq, an elegant, flowing form of calligraphy. This manuscript is somewhat unusual in its archaizing use of the more rectilinear naskh script. Nevertheless, the paintings of this manuscript are stylistically akin to those found in manuscripts produced in Shiraz during the reign of Sultan Khalil Aq Quyunlu (d. 1478), suggesting that it was copied under an earlier patron, but illustrated in the Aq Quyunlu period.
